IMPROVEMENT IN CARRIAGE-WHEELS.

Specification forming part of Letters Patent No. 127,063, dated May 211872.

Specification describing a new anduseful Improvement in Wheels, inventedby JAMES A. JOHNSTON, of Topeka, in the county of Shawnee and State ofKansas.

The invention will be first fully described and then clearly pointed outin the claim.

Figure 1 of drawing is a plan View withnut oft. Fig. 2 is a longitudinalsection of hub attached to spokes.

A represents the section of a double hub, provided with body a andprojecting tube a threaded on the outside of end a but having apolygonal or angled perimeter at a adjacent to the body. B is a ring ofrubber or other elastic substance. 0 is another section of hub, madepolygonal on the inside surface 0. D is a nut. E E are two sets ofspokes, one on each section of hub, but all fastened within the same rimF. The section A is applied to section 0 so that the tube a willprotrude therethrough, and the polygonal part a of tube will fit snuglywithin the polygonal surface 0 of the section 0. The nut D is thenscrewed on and the sections brought as near together as is requisite toproperly tighten the spokes and hold them firmly in position. Betweenthese sections of hub there may be used rigid spacing rings or pieces,adjustable or otherwise, but I prefer to employ the elastic ring B,because nothing is then needed in case of spokes working loose but toscrew the nut up against it until the looseness is fully taken up andthe tire fully tightened.

Having thus described all that is necessary to a full understanding ofmy invention, What I esteem to be new, and desire to protect by LettersPatent, is

l. The sections A C of a hub, constructed and combined with a nut, D,and elastic ring, as and for the purpose described.

2. The sections A O, constructed and adjustable one on the other, incombination with an intermediate elastic ring, B, as and for the purposeset forth.
